ws2_32: Patch to selectively bind to interfaces while still allowing broadcast packets (try 2)

Description:
    I know it's been quite a while, but I'm back with another solution
for Bug #7929.  This patch uses SO_BINDTODEVICE in order to bind a
socket to a specific interface while still allowing broadcast packets
(a Linux-only feature).  While this feature normally requires root
privileges, it can also be enabled by giving wine-preloader the
CAP_NET_RAW capability.  Should insufficient permissions be available,
the patch outputs an appropriate error message notifying the user that
broadcast packets will not function properly.

    ws2_32: Patch to selectively bind to interfaces while still
allowing broadcast packets.
